Energy Storage
At a Glance
Firefly Solar designs and installs residential and commercial energy storage systems for homes and businesses across Canada. We size each battery system to your energy usage, backup requirements, and solar production, then deliver end-to-end service.
Backup Power
Keep critical loads running during grid outages. Lights, fridge, internet, and medical equipment stay powered automatically.
Solar Battery Storage
Store excess solar energy for evening and overnight use. Maximize your solar self-consumption and reduce grid dependence.
Peak Shaving
Reduce demand charges for commercial properties. Discharge stored energy during peak rate periods to lower electricity costs.
Off-Grid Systems
Complete energy independence for remote properties. Pair with solar for fully self-sufficient power in locations without grid access.
Why Batteries
Why Canadian Homeowners Choose Battery Storage
Grid Power Isn't Guaranteed
Ice storms in Ontario. Chinooks in Alberta. Winter storms across BC. Canadian homeowners face power outages, sometimes for days. A whole-home battery backup system keeps your critical loads running when neighbours go dark.
No fuel storage, no manual startup. The system activates automatically within milliseconds of detecting a grid failure, keeping your family safe and comfortable through any outage.
Regional Advantages
Battery Storage Benefits by Province
Alberta
Alberta's deregulated electricity market means prices fluctuate throughout the day. Battery storage lets you buy low and use high.
With increasing extreme weather events and grid strain, backup power provides essential protection for Calgary, Edmonton, and rural Alberta homes. The province's growing renewable energy sector also means more opportunities to pair solar with storage for maximum savings.

Business Solutions
Commercial Battery Storage
Commercial battery storage addresses peak demand charges, provides operational resilience, and generates revenue through utility programs.
Peak Demand Management
Batteries offset demand charges which often represent 30 to 50% of commercial electricity costs.
Reduce peak demand by discharging stored energy during high-consumption periods, significantly lowering your utility bills without changing how your business operates.
Time-of-Use Arbitrage
Store inexpensive off-peak electricity and discharge during expensive peak periods.
Automated systems optimize charge and discharge cycles based on your utility rate structure for maximum savings, all without manual intervention.
Operational Resilience
Bridge power during outages. Protect sensitive equipment. Maintain business continuity.
Commercial battery storage keeps critical operations running when the grid fails, preventing costly downtime and protecting against data loss or equipment damage.
